    Production Features

    1. Internal o-rings to ensure water ingress protection.

    2. NAMUR standard for all sizes for assembly of switch boxes and positioners.

    3. Threaded parts in front and the back side of the body for easy assembly of a pneumatic control panel.

    4. Round rolled is used, reducing the friction between the yoke arm and pin, minimizing the wear.

    5. Replaceable bearings protect the sliding and rotating components, suitable for either dry or lubricated working conditions.

    6. PTFE thrust bar prevents yoke pin axial movement, transuferring axial loads directly to the drive module case.

    7. Connects the piston rod with the guide block, compensating for side load deflection and reducing wear on rod, bearings and seals.

    8. CYLINDER The inner surface of cylinder is coated by PTFE, to prevent resistance and self-lubricating.

    9. PISTONS SEALS Double sealing, with o´ring and dynamic ring to prevent metal to metal contact between the piston and the cylinder.

    10. SPRING MODULE Safe spring Lock, prevents spring module detachment from the drive module.

    11. SPRING MODULE Internal Hydraulic cylinder for manual pump override.
